Box



Patented July 15, 1930 UNITED STATES HARRISON B. WALTER, OF CHICAGO,ILLINOIS, ASSIGNOR TO CONTAINER CORPORA- PATENT OFFICE TION OF AMERICA,OF CHICAGO, ILLINOIS, A. CORPORATION OF .DELAWARE BOX Application filedJune 27,

The present invention relates to containers and more particularly tocartons or boxes constructed of paper, fibre or other light material.One object of the invention is the provision of a box or carton whichcan be made substantially from a one-piece blank in which the materialis distributed and arranged in such a manner that the box is of a sturdyconstruction throughout and is especially strengthened at parts whichare likely to be subjected to the greatest crushing forces. Anotherobject is to provide a box or carton of the character described whichprovides a maximum of strength of parts with a minimum of materialemployed. Other objects are to provide a box which may be speedily andeconomically manufactured and assembled ready for use.

To these and other ends the invention resides in certain improvementsand cornbina tions of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings:

Fig. 1 is a perspective View showing the box assembled Fig. 2 is a viewof the box blank, and Fig. 3 is a perspective detail view of a partitionmember for use with the box.

Similar reference numerals throughout the several views indicate thesame parts.

The present embodiment of the invention provides a box construction ofthe class described which is strong and durable and at the same timelight and easily handled, being particularly advantageous in the packingof light, fragile goodssuch as crackers and waters zamongotherithings.The box may be made from substantially a one-piece blank which-may be;handled inflat condition until such-time .as it is desired to assembleand use the-same.

Referring inore particularl to the draw- 'ings,-numeral-10'indicates theox as a whole, which is' preferably. formed of solid fibreboard',"-althou-gh .anytype of material such a's'cardboard' oricorrugated board, for example, may be employed'to equal advantage.

formed from a blank such as illustrated in Fig. 2. In the presentinstance, this blank is ends and sides being separated from the bottomby score lines 14, 14 along which the sides and ends may be bentupwardly in assemblingthe box. Extending from the sides of the end walls12 are flaps 15, 15 of a width approximately equal to the width of theend walls, and of a length equal to substantially one-half of the lengthof side walls 13 for a purpose which will be presently brought out. Theend walls 12 are each provided with an extension 16 which serves toclose the opening between wall 12 and the cover of the box when the boxhas been set up. One of the side walls 13 is preferably provided with arelatively narrow flap extension 17, similar to the extensions 16, andthe other side wall 13 is preferably formed with a relatively wideextension 18 which serves as the cover for the box. The blank isprovided with suitable slits 19, 19 which separate the flaps 15, 15 fromthe side walls 13, 13.

The extensions 16 and 17, the cover 18, as well as the flaps 15 are allseparated from their respective walls by means of score lines 20 alongwhich the parts may be readily bent in a manner which is wellunderstood.

In forming the box, the sides 13, 13 and the sides 12, 12 are bentinwardly at right angles to the bottom 11 and the flaps 15 are broughtinwardly so as to lie inside of and against the long side walls 13 towhich they may be secured in any (1 asired manner. In the presentinstance, the flaps 15 are secured to the side walls by means of staples21.

' The flaps 15 may somewhat overlap or may be made to exactly abut eachother at the vertical central part of the long sides 13, but in thepreferred form of the invention these flaps are formed of such a lengththat, when the box is assembled, their adjacent free ends are slightlyspaced from each other. While the flaps 15, 15 are preferably of such alength as to terminate substantially centrally of the side walls, theparticular point at which the flaps te'rminateis more or le s immat rialso lon as the flaps cover substantially the area 0 the side walls.

For the purpose of strengthening the box to prevent its being crushedunder objects placed thereon, and to form compartments within the box,there is preferably provided a partition member 22 disposed transverselythe box and abutting with its respective ends against the sidewalls at apoint between the adjacent ends of the flaps 15, which ends also serveas abutments to prevent lateral displacement of' the partition.

The partition 22 may, if desired, be provided with means whereby it maybe interlocked with the side walls of the box. To this end an extension23 is provided at each end of the partition, which is adapted to be bentover so as to lie between the side wall and the end portion of one ofthe flaps 15. To facilitate the insertion of the extension 23 betweenthe wall 13 and the end of the flap 15, at least one of the flaps 15 oneach side of the box is secured thereto so as to have a substantialportion of its end free from the side 13, as clearly indicated in Fig.1.

The partition may be inserted in place by sliding it downwardly afterengaging the extension 23 behind'the free end portions of the flaps 15.With this construction of the partition it may be easily secured inposition without danger of it being displace-d. The free end of one ofthe flaps 15 engages over the extension 23 and abuts the partition 22 onone side and the end of the other flap 15 abuts the partition 0n theother side, see Fig. 1. The partition 22 may be formed of any desiredmaterial, but it is preferably formed from the same material of whichthe box 10 is constructed.

After the goods have been placed within the box, the flaps 16, 16 and 17are folded inwardly over the contents and the cover 18 is then swungdownwardly into position where it may be secured in any desired manner.as by means of ordinary gummed tape.

The present invention thus provides a box having relatively short endsand relatively long sides, the latter of which are reinforced by flapssecured thereto, which provide, in effect, with the wall 13, a side wallof double thickness which effectively resists all but the most severecrushing strains. With the part tion 22 in place and the box in sealedconditlon, the partition is securely interlocked with the side walls,and the cover will contact at its middle with the partition and will besupported by it so that the box is able to sustain relatively heavyblows or pressure without collapsing sufficiently to injure the materialcarried therein.

While the present description sets forth a preferred embodiment of theinvention, numerous changes may be made in the construction withoutdeparting from the spirit of the invention, and it is therefore desiredthat the present embodiment be considered in all respects asillustrative and not restrictive, reference being had to the appendedclaims rather than to the foregoing description to indicate the scope ofthe invention.

Having described my invention, I claim:

1. A box comprising a bottom, side walls and end walls integraltherewith, reinforcing flaps integral with said end walls, and adaptedto be secured against said side walls to reinforce the same, the ends ofsaid flaps terminating adjacent the mid-portion of said side walls,means for securing said flaps to said side walls, one of said flaps oneach side of said box having a free, unsecured portion adjacent its end,a partition disposed transversely said box, said partition havinglaterally projecting extenslons at each end, each extension beingadapted to lie between one side of the box and the free end of the flapsecured thereto.

2. A box comprising a bottom, side walls and end walls integraltherewith, reinforcing flaps integral with said end walls and adapted tobe secured against and reinforce said side walls, the adjacent ends ofsaid flaps being somewhat separated from each other and terminatingadjacent the middle of said side walls, means securing said flaps to theinterior of said side walls along lines spaced from the ends of saidflaps, a transversely disposed partition in said box, a laterallyextended portion on at least one end of said partition adapted to liebetween the side wall and an adjacent free end portion of one of theflaps.

3. A box comprising a bottom, side walls and end walls integraltherewith, reinforcing flaps integral with said end walls, and adaptedto be secured to said side walls to reinforce the same, the ends of saidflaps terminating adjacent the mid-portion of said side walls. meanssecuring said flaps to the interior of said side walls, and a partitiondisposed transversely said box, the ends of said flaps being spaced fromeach other the thickness of said partition, whereby said ends serve asabutments to retain said partitions from displacement.

4. A box comprising a bottom, four walls integral therewith, reinforcingflaps integral with each of an oppositely disposed pair of said walls,said flaps being adapted to be secured to the remainin walls toreinforce the same, the ends of sai flaps terminating adjacent the.mid-portion of said remaining 'walls, means securing said flaps to theinterior of said remaining walls, a partition disposed across the saidbox, and means for interlocking the ends of said artition with the freeends of at least one 0 said reinforcing flaps at opposite sides of saidbox.
